BITMAIN Antminer S1 support and OverClocking thread

[Aurum]

The formula for HW % is HW/(diffA+diffR+HW)*100  correct?  

I assume it looks more like HW/((diffA+diffR+HW)*100)  given that multiplication comes before division.

never wrote it down I just use a website. http://www.coincadence.com/antminer-s1-hardware-error/
Formula: Error % = HW / ( HW + DiffA + DiffR) * 100

Thanks. That's a great tool.  This is rather disheartening however.  Any attempt at overclocking results in at least 14% HW errors.

Why ignore DiffS ? I use: Error % = 100 x HW / (HW + DiffA + DiffR + DiffS)

I can OC all 35 of my S1s to 375, a few to 387 and a couple to 393. Anything higher does not work.

From the Antminer U1 overclock manual.

Let's see the example of why 0780 and 4F81 are 400MHz.

HEX                   BINARY                          15/BS         M                               N                            OD
0780                 0000  0111  1000  0000       00          00 0111 1   = 15          000 00  = 0              00 = 0 which NO=1
4F81                 0100  1111  1000  0001       01          00 1111 1   = 31          000 00  = 0              01 = 1 which NO=2
5F82                 0101  1111  1000  0010       01          01 1111 1   = 63          000 00  = 0              10 = 2 which NO=4

Fout = 25 * (M+1) / ((N+1)*NO)

Fout(0780) = 25 * (15+1) / (1*1) = (25*16)/1 = 400 MHz
Fout(4F81) = 25 * (31+1) / (1*2) = (25*32)/2 = 400 MHz
Fout(5F82) = 25 * (63+1) / (1*4) = (25*64)/4 = 400 MHz

Actually, 5F82 is also 400 MHz, but due to the instruction below 500 <= Fout * NO <=1000
Fout(5F82) = 400MHz, therefore,  Fout*4 = 1600 and over 1000.

So I think I should not config 5F82 for 400MHz, according to this manual.
I don't say that it does not work (I tried it before understanding the HEX, it worked)
but you have also another 2 freq_values which give you the same MHz and get along with the instruction in the manual.

Any questions are welcome.

What would be some FOUTs to fill out this little table    E.g., 222.5, 220, and/or 217.5. TIA

Has anyone ever tried clocking an S1 beyond 400 MHz? Bitmain docs give settings info to clock up to 500 MHz. If anyone has tried let me know the power draw and hash rate and error rates you were getting. Thanks.

I had some trouble with an S2 recently. Fixed it with an off the shelf Beaglebone Black.

As per datasheet 400M is very much possible. But the issue is with HWE%, it will be huge.
Also the huge power consumption will not make it run profitably.
Further, the DC-DC voltage converters will not be able to handle that much and will overheat and fail.
No where heard anyone did it successfully for a prolonged period. If you are trying it don't forget to update the result.

That's great. You got a special S1.
My S1 will give 0.7% HWE much before that.
At stock clock itself my temperatures are at 40-45.

It is a special little unit that's for sure. In return I've looked after it with nice big second fan and heatsinks all round.

What would be the most optimal settings for the S2 with a 1200W Psu and excellent ambient cooling?

I have some small heatsinks that would fit the DCDC, do you think it would make a small difference in efficiency and DCDC stability?

it should help with keeping them cooler and running with less errors. go ahead and do it. I've got them on all of mine and it runs 406mhz all day long.

Any thought if that would help the DC-DC issue the early S3's have? cool em down and maybe you can pull a bit more juice from them?

possibly, Bitmain tend to under spec those parts to save money. I considered sourcing some higher rated ones to overclock the s1 further, it's getting to the limit of my electronics knowledge though.
Put it this way, it couldn't hurt them lol

Hello tell me the reason for my fan speed does not reset.  Thats when cold then immediately grows And does not reset when the temperature is 35 or 45 shows in 3720 within 3480  Thank you  if daste answer.

Downclock you Ant and restart your miner after shutting off for 10 minutes.
I mean do a power cycle. Then check whether the fan speeds now.
Now set your Ant S1 at stock clock and check fan speed after a restart.
If fan responds properly, clock to previous frequency and check the fans now.

I don't think just cooling down the DC-DC controller will bailout the Antminer S3 problem.
It may increase the hashrate a little bit more or help to hash it with more stability.
I'm designing a setup to cool the DC-DC controller extremely down with heatsink and water cooling pipe setup.
No high expectations but checking whether it can hold at 504Ghs or 478Ghs or atleast stable at 441Ghs.
Will try it at S1 before moving to S3. Now I'm searching for some small copper pipes, do anyone know a source to get it?

Sorry if this was already asked, I just couldn't find it anywhere.  But here's my question:  Are you able to clock the Antminer S1 at a frequency that isn't something like  350, 375, 400, etc.  Something in-between those numbers.  I recently received an Antminer S1 and had it clocked to 375 because my PSU doesn't have enough watts on the 12 volt rail to go to 400.  I want to get the most out of my miner before it becomes non-profitable though, so can I clock it to something like 380 or 390?  I think I remember someone doing 389.9 because it ran better than 400, not too sure.  Thanks and sorry if this is a stupid question, I'm new to Antminers a bit.

hi, I have several S1's and if needed, can always get them to reset to 192.168.1.99... I just recently took one outside and blew it with air to get some cat hair out of it and when I went to hook it up, it would not mine, so I tried to do the reset button every which way and it won't reset... for some reason the orange light won't come on the  network plug... I have tried multiple network cables, ports, psu's and no matter what can't get the thing to reset... I am at my wits end and don't know what to do... it just won't reset and turn the orange light on - its like it needs to be shocked or reset, but the reset button and holding it down and restarting isn't doing the trick, any suggestions?
